+     <title>Frame Buffer Library</title>
+
+     <para>
+       The frame buffer drivers depend heavily on four data structures.
+       These structures are declared in include/linux/fb.h.  They are
+       fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs.
+       The last three can be made available to and from userland.
+     </para>
+
+     <para>
+       fb_info defines the current state of a particular video card.
+       Inside fb_info, there exists a fb_ops structure which is a
+       collection of needed functions to make fbdev and fbcon work.
+       fb_info is only visible to the kernel.
+     </para>
+
+     <para>
+       fb_var_screeninfo is used to describe the features of a video card
+       that are user defined.  With fb_var_screeninfo, things such as
+       depth and the resolution may be defined.
+     </para>
+
+     <para>
+       The next structure is fb_fix_screeninfo. This defines the
+       properties of a card that are created when a mode is set and can't
+       be changed otherwise.  A good example of this is the start of the
+       frame buffer memory.  This "locks" the address of the frame buffer
+       memory, so that it cannot be changed or moved.
+     </para>
+
+     <para>
+       The last structure is fb_monospecs. In the old API, there was
+       little importance for fb_monospecs. This allowed for forbidden things
+       such as setting a mode of 800x600 on a fix frequency monitor. With
+       the new API, fb_monospecs prevents such things, and if used
+       correctly, can prevent a monitor from being cooked.  fb_monospecs
+       will not be useful until kernels 2.5.x.

+       interface:  basically a multiplexed shift register.

-       The frame buffer drivers depend heavily on four data structures.  
-       These structures are declared in include/linux/fb.h.  They are 
-       fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs. 
-       The last three can be made available to and from userland. 
-     </para>
-
-     <para>
-       fb_info defines the current state of a particular video card. 
-       Inside fb_info, there exists a fb_ops structure which is a 
-       collection of needed functions to make fbdev and fbcon work.
-       fb_info is only visible to the kernel.
-     </para>
-
-     <para>
-       fb_var_screeninfo is used to describe the features of a video card 
-       that are user defined.  With fb_var_screeninfo, things such as
-       depth and the resolution may be defined.
-     </para>
-
-     <para>
-       The next structure is fb_fix_screeninfo. This defines the 
-       properties of a card that are created when a mode is set and can't 
-       be changed otherwise.  A good example of this is the start of the 
-       frame buffer memory.  This "locks" the address of the frame buffer
-       memory, so that it cannot be changed or moved.
-     </para>
-
-     <para>
-       The last structure is fb_monospecs. In the old API, there was 
-       little importance for fb_monospecs. This allowed for forbidden things 
-       such as setting a mode of 800x600 on a fix frequency monitor. With 
-       the new API, fb_monospecs prevents such things, and if used 
-       correctly, can prevent a monitor from being cooked.  fb_monospecs
-       will not be useful until kernels 2.5.x.
